SPECIFICATION forming part of Letters Patent No. 786,575, dated April 4,1905. Application filed November 23, 1904. Serial No. 234,035.

To all 1/710711 if III/Ill] concern:

Be it known that l. ARTHUR Liesonurz, a citizen of the United States,residing in the city of St. Louis and State of Missouri, have invented accrtain ncw, useful, and Improved ('ast-Steel Car-Truck, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming-a partof this specification, in which i Figure l is a side elevation of acar-truck ei'nbodying my invention. Fig. 2 is a plan view of onehalf ofthe car-truck, the truckbolster having been removed to disclose thespring-seal. which is formed upon the truck beam or side frame. Fig. 3is an end elevation of the truck, one-half thereof being in verticalsection on the lines 3 8" of Fig. 1. Fig. i is a transverse verticalsection of the side or truck beam on the line B P of Figs. 1 and Q, andFig. 5 is a detailed side elevation of the truck-beam above referred to.

This invention relates to railway-trucks composed of metal, and hasspecial reference to improvements in trucks of that class where-- in thejournal-boxes are rigidly secured in the truck-frame and whercin'thetruck-bol--- ster is supported by springs upon the side f'ames of thetruck as distinguished from those trucks wherein the bolster issupported bytransverse transoms. in a truck of this general class thetruck-bolster is generally quite as long as the car-axles, and its endsextend through or be 0nd the side frames, the springs for supporting thebolster being arranged substantially in the vertical planes of the saidframes. c

My invention relates particularly to improvements in the side frames oftrucks,

. though not particularly or specially confine-d to such parts.

The object of the invention is to provide a car-truck which shall be of.less weight and cost than others of this class and which shall he.composed of fewer parts.

Another and distinct object of the inveniion is to so improve theconstruction of the side frames of car-trucks as to provide ample spacesfor the bolster-springs and yet afford ample strength, and. furthermore,enable the the placement and the removal of the bolster withoutrequiring the side frames to be taken down or dismembered. r

A further objectof my invention is to provide a bolster supporting andguiding Ll'utgli frame or beam that may be made in a single piece. I

The particular object of the invention is to proride'a. car-truck inwhich the usual transoms shall be dispensed with and in whichsingle-part truck-beams, one on each side of the truck, shalltake theplace of the arch-bars, truck-columns, spring-seats, and minorassociated parts commonly used to connect the journal-boxes of a truckand support the ends of the truck-bolster.

ventioh is to provide scar-truck of the described class'whereof thechief members may be made of cast-steel.

Broadly defined, my invention consists in a 'car-truck'thatischaracterized by side beams which have tops that are adapted to guideandsupport the truck-bolster and the ends of which beams restupon and aresecured to the tops of the journalboxes of the truck, and a further:characteristic of my invention is that the bolster end guide openings orjaws in the sides of mytruck are. open at the top, so that the bolstermay lie-removed without disturb ing any other part of the, truck exceptthe light detachable bolstea-stops.

Specifically dclincthmy invention embraces and resides in a truck havingsidc beams that are provided with upwardly-extcnding bolster-columns andan expanded or widened top, which latter is preferably integral with thebeam and serves as the seat for the bolstersprings. The side membersthus equipped with spring-seats and bolster-guides l generally make ofcast-steel, and my invention desire, however, to state that though Iprefer that eacl. distinct complete member of my truck shall be a singlemetal, preferably steel, casting, said membe'rsmay be constructed of oneor more pieces of rolled, pressed, or cast metal, and I do not limit myinvention to a A further and particular object of the in takes itsspecial name from these castings.

Because of this shnpez'of, the beams the bolsten. is,in effect, swung or hung lroin the tops of the journal-boxes, and itslateral thrusthas little torsional effect upon the hlHClPlJQ-RER'IS. Theupper and lower chords or webs l0 end with the body of the beam.

Theends of the beam are straight and rest squarely upon the tor ot' thejGLllZDQl'bOXQS. The bottom of the beam is substantially in the plane ofthe bottoms of the journal-boxes, end the tie-oar 5 is bolted orotherwise secured to the lizo-ttom flange 11' of the truck-beams.

Referring to Fi 5, it will be seen that the side beam is provided with abolster-space that is open at the top, being formed by the jaws orcolumns 1% that rise from the ten of the beam.

, beams and hangers.

and, with a simple bar, constitutes the means for securing the bolsterand spring in proper place. In addition to these functions I make theside beams of my truck toperform the further service of supporting thebrake-beams of-the truck- The brake mechanism of the truck is not shownin the drawings; but it will be seen that each truck-beam is providedwith two vertical bracket-likewebs 19, arranged upon the upper innerside thereof 'abovethe top web 10. These brackets 19 are preferablyintegral with the columns or bolster-guide 14 and areprovided with lugs20, having holes for pins and adapted to support the brake- Thus thecolumns or the spring-seat plate, or

both, may be formed separately and bolted or fastened upon the top ofthe beam proper.

This is alsotrue of the brake-hanger lugs,

and it is also obvious that both the longitudinal and the cross-sectionof the truck-beam,

as herein shown, may be modified to meet special requirements, andgenerally, as it is obvious that numerous modifications of my inventionwill readily suggest themselves to one skilled in theart, I do notconfine the invention to. the specific constructions herein shownanddescribed. I
